Images from 30 inch by Kaz Sekiguchi covering the period of the flash from the impact of fragment Q2 on July 20. Sequence starts on July 20 2019 UT and the interval between images is 40 sec. The exposure time was 10 sec, hence the noisy background. Some of the later images suffer from double imaging due to telescope wind-shake. The impression of the observers was that this flash was brighter than any other so far, but the flash was of shorter duration. The sequence stops before the end of the event.
